I've been on Yaz for a year now, been on Yasmin for about 5 years before that. I started my sexual life just last year, and been very carefull. Last two weeks, i went to visit my boyfriend abroad, and decided to try and have sex without the condom (we both checked no std's). Anyway, I'm a sunday starter, and had my last 4 inactive pills from aug 14th to 18th, and had my period starting from 17th to roughly around the 20th. All this time i took my pills, as i should have, exact same time. However today (saturday), when i had to take my pill i noticed the friday pill was missed (even though i could have sworn i took it) so i took both friday and saturday toghether. My worry is i had unproteted sex on the 22nd of august. How high would be the chances of a pregnancy? The yaz leaflet in my native language gives a different info than the one found online..so im confused.
